Bristol based business Slingshot Effect is planning to expanding its urban street games firm in the UK and the US after sell a out season last year.

The creative tech firm sells fun nights out by turning run of the mill city streets from London to Newcastle and Glasgow into alternative backdrops for a piece of fictional storytelling.

Co-founders Simon Johnson and Simon Evans hire actors and hundreds of voulunteers in each city, who become street chasing zombies for the night as customers try to solve puzzles and navigate street maps to safety.

The five year old business’s ‘2.8 Hours later’ game (www.2.8hourslater.co) /has become a bestseller, with tickets costing between £28 and £60.

But Slingshot Effect also has plans to develop a London Dungeons game based on Jekyll and Hyde called Jekyll 2.0, and raise crowdfunding to fund a push into America.

Co-founder Simon Evans said: ‘We use tech and artistic skills to change the experience people have of ordinary City streets as the game combines mobile computing combined with mini performances. Success depends on the decisions you make with all the information available.’

‘We have been really encouraged by the appeal of the game to lots of different ages from 18 upwards. Just as many women as men play and from all sorts of backgrounds.’

So far the firm has been supported by the Arts Council and TSB funding, but as a business turnover has grown from just £19,000 in 2009 to an expected £815,000 this year.
